The board may decline to grant, or may suspend or revoke, a weighing or measuring permit, a tester's certificate or a weighing and sampling certificate, where the applicant therefor, or holder thereof, has violated any provision of this act for the weighing, measuring, testing or sampling of milk, or has violated any rules, regulations or orders of the board respecting the weighing, measuring, testing or sampling of milk, or has engaged in any practice with respect thereto which causes milk producers to be underpaid for their milk, or which causes stores or consumers to overpay for such milk, or which otherwise defrauds or tends to defraud milk producers, stores or milk consumers.

The procedure before the board and of the board, with respect to the refusal, suspension or revocation provided for herein, and the procedure governing appeals from such action of the board, shall be as that prescribed in this act with respect to milk dealers' licenses issued hereunder.
